1. A flat panel detector comprising:
a first optical assembly, having a first side and a second side opposite to the first side in a thickness direction of the flat panel detector, and comprising:
a first scintillator layer configured for converting at least part of rays into a first visible light; and
a first light guide component stacked with the first scintillator layer and configured for guiding the first visible light;
a first image sensor assembly stacked with the first optical assembly, configured for receiving the first visible light, and comprising:
a first image sensor located at the first side of the first optical assembly; and
a second image sensor located at the second side of the first optical assembly, wherein:
the first image sensor comprises:
a first display region comprising a plurality of first wires;
a first non-display region surrounding the first display region, wherein the first non-display region comprises a first connection part, a first connection wire corresponding to the first wire is provided in the first connection part, and the first connection wire is electrically connected with the first wire;
the second image sensor comprises:
a second display region comprising a second wire;
a second non-display region surrounding the second display region, wherein the second non-display region comprises a second connection part, a second connection wire corresponding to a second wire is provided in the second connection part, and the second connection wire is electrically connected with the second wire;
in the thickness direction of the flat panel detector, the first display region and the second display region overlap with each other, and the first connection part and the second connection part do not overlap with each other.
